Nexen N Fera Primus - 215/55 R18 95V

215 is the tire width in millimeters, 55 is the aspect ratio (height as a percentage of width), R means radial construction, 18 is the wheel diameter in inches, 95 is the load index, and V is the speed rating.

The 'Wear Eye' is a visual aid integrated into the tread pattern. When the tread surface becomes level with the 'Wear Eye', it indicates the tire has reached its wear limit and should be replaced.

The N Fera Primus is designed for strong performance in wet and dry conditions. For regions with severe winter weather, dedicated winter tires are recommended.

It is generally recommended to use matching tires on all four wheel positions for optimal performance and safety. Mixing tire types can negatively affect handling and stability.

Always refer to your vehicle's owner's manual or the sticker on the driver's side doorjamb for the recommended tire pressure. Never exceed the maximum pressure indicated on the tire sidewall.

Tire rotation is typically recommended every 5,000 to 7,000 miles to ensure even wear and maximize tire lifespan. Consult your vehicle's maintenance schedule for specific guidelines.

The 3+1 wide grooves are designed for efficient water evacuation, significantly reducing the risk of hydroplaning and improving traction on wet roads.

Check wheel alignment and tire balance. Ensure proper tire pressure is maintained and follow the recommended rotation schedule.

Verify tire pressure. Road noise can sometimes increase as tires approach the end of their service life or if debris is embedded in the tread.

Check tread depth using the 'Wear Eye' indicator. Ensure tires are inflated to the correct pressure. Consult a professional if the issue persists.

Ensure tires are properly inflated and that the tread depth is sufficient. The 3+1 wide grooves are designed to combat hydroplaning, but extreme water conditions can still pose a risk.
